Abstract:

Energy transfer reactions of electronically excited atomic and diatomic species were studied. The excited species were created by vacuum ultraviolet irradiation of simple molecules, with image-tube spectrographs and filtered photomultipliers being utilized to detect and monitor emission features. Quantum yields for excited states were deduced from absolute intensity measurements. A pulsed photolysis-signal integration system was used to determine absolute rate coefficients for energy transfer reactions of Osinglet S, N2A triplet Sigmau, and Ndoublet D. Osinglet D and COA singlet Pi were also studied. Resonance fluorescence scattering was used to measure Otriplet P, COX singlet Sigma, and NOX doublet Pir. Author
